About the alternate gamma types
Next to the standard gamma correction, the projectors can be manipulated in a way to simulate gamma types
for other devices or purposes. This includes sRGB (standard Red-Green-Blue), Power gamma and a number
of DICOM gamma ranges.
DICOM gamma ranges are usually reserved for medical displays. While this projector is not a certified DICOM
display, it can simulate certain specific DICOM gammas at a few selected max light outputs. The DICOM
gamma assumes that both ambient light and the projector outputs black as 0 cd/m². Then there will be a few
predefined gamma curves at the following light outputs:
• DICOM 10: 10 cd/m²
• DICOM 60: 60 cd/m²
• DICOM 180: 180 cd/m²
• DICOM 250: 250 cd/m²
• DICOM 300: 300 cd/m²
• DICOM 400: 400 cd/m²
Take into account that the available DICOM gamma types may be more limited than this list, depend
on your used projector type.
Exception when using an HDR source
The only alternate color gamma that can not be selected in this menu is PQ/HDR. Because the color output of
HDR is dependant on extra factors such as screen luminance, a separate menu has been made available for
this (PQ).
If the source signal is HDR encoded an HDR icon will be visible next to the source signal. This is visible both in
the Connector selection menu, as well as the status menu.
